Giving a Razor/Honing Demo at local museum, suggestions needed

[57vert]

So next month I am scheduled to give a razor demonstration at my local museum. They have a nice antique barbershop display with a few chairs, SRs, shaving mugs....

I think I'm basically just going to sit there and hone a few razors and answer questions as people have them for me. I'll take a few DE, SE, and SR with me to show the variety. I have a couple shadow boxes to mount them in so folks can see....but not touch. Any suggestions on displays I can make (and printable sources) for the different point styles, blade styles, etc.

Anything else you think I should do or be ready for would be helpful.
